favorite IOS command
Debug all, seems like a good idea, but the "sir, yes sir!" response of the router is dead on.
Anytime IOS is mentioned, I have to discuss my favorite IOS command: "rel in 5" (reload in 5 minutes). Saved my bacon on more than one occasion, especially when working on a remote router.
Issue the command, do the commands that will possibly drop the route that allows you to access the router, then see if all is well. If you borked a comnand, you sweat out a brief period of "suboptimal route selection resulting in degraded performance". If things are good, do a "rel can" (cancel the reload). At that point, if you're me, you log off and go home happy (until the next time the power cycles and you realize you forgot to do a "wri mem").
Anon, hoping that my old bosses don't recognize my router excuse.
